90712289 ÷ 893 
The aim is to understand the frequency of 893 in 90712289.

Going ahead to step 1:
When dividing 9 by 893, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 893

Step 2:
90 divided by 893 is 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Bring next digit (7) of the dividend behind the 90 and repeat the process: 907 / 893

Advancing to step 3:
893 can be fit into 907 1 times, resulting in a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 14 after subtracting 893 from 907.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 893

Moving on to step 4:
893 can be fit into 141 0 times, resulting in a remainder of 141.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 141, we get 141.
Grab the next digit (2) from the dividend, add it to 141, then carry on: 1412 / 893

Let's proceed to step 5:
The number 893 fits into 1412 1 times, leaving a remainder of 519.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Subtract 893 from 1412 to get 519.
Grab the next digit (2) from the dividend, add it to 519, then carry on: 5192 / 893

Step 6:
5192 divided by 893 is 5 with a remainder of 727.
Record the quotient 5 as the next digit in the result. 
Result so far: 1015.0
If we subtract 4465 from 5192, we get 727.
Grab the next digit (8) from the dividend, add it to 727, then carry on: 7278 / 893

On to step 7:
893 can be fit into 7278 8 times, resulting in a remainder of 134.
The next digit of our result is 8. 
Result so far: 10158.0
Deduct 7144 from 7278 and we're left with 134.
Fetch the next digit (9) from the dividend, attach it to 134 and continue: 1349 / 893

Step 8:
1349 divided by 893 is 1 with a remainder of 456.
Use 1 as the next digit of our solution. 
Result so far: 101581.0
The remainder is 456 after subtracting 893 from 1349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Going ahead to step 9:
When dividing 4560 by 893, we get 5 with a remainder of 95.
The next digit of our result is 5. 
Result so far: 101581.5
If we take 4465 away from 4560, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 10:
893 goes into 950 1 times with a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 101581.51
Deduct 893 from 950 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 11:
570 divided by 893 is 0 with a remainder of 570.
Put 0 as the next digit of the answer. 
Result so far: 101581.51
If we subtract 0 from 570, we get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Let's proceed to step 12:
The number 893 fits into 5700 6 times, leaving a remainder of 342.
The next digit of our result is 6. 
Result so far: 101581.5106
Deduct 5358 from 5700 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Let's proceed to step 13:
The number 893 fits into 3420 3 times, leaving a remainder of 741.
Use 3 as the next digit of our solution. 
Result so far: 101581.51063
If we subtract 2679 from 3420, we get 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7410, and continue the process.

Advancing to step 14:
7410 divided by 893 is 8 with a remainder of 266.
Use 8 as the next digit of our solution. 
Result so far: 101581.510638
If we subtract 7144 from 7410, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Advancing to step 15:
893 can be fit into 2660 2 times, resulting in a remainder of 874.
The number 2 becomes the next digit in our result. 
Result so far: 101581.5106382
Subtract 1786 from 2660 to get 874.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8740, and continue the process.

Let's proceed to step 16:
893 goes into 8740 9 times with a remainder of 703.
Use 9 as the next digit of our solution. 
Result so far: 101581.51063829
Subtracting 8037 from 8740 leaves us with 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

After the division, we end up with 101581.51063829 and a remainder of 7.03e-07.
